Hello guys.

I had a windows instalation int otwo 128gb ssds and I decided to revert this raid and perform a clean instalation into one of them. Im acutally using it normally but the other looks really strange:


  • - Still pointed as 238gb instead of 119 like the other one
    - When I open the windows disk manager it asks me to initialize the disk but when I select MBR it gives me a "data error cyclic redundancy check" error

I have no idea where to go now. OFC I dont want the lost data.. I just want to use the drive.

I have already gone to Diskpart > List disk > Select disk 2 > clean .. it says that Diskpart is cleaning the disk but well.. many minutes ago and nothing changed.

You can't break a RAID 0 without losing data. If you already took one of the drives and installed Windows on it then the data is lost - period. Also, you didn't say how the RAID was created.

Remove all drives that have data on them that you want to save.
POST with just the drive that you want to recover (the one showing disconnected).
Go into the RAID config (usually something like CTRL A. This is right after POST but before the OS starts to load) and kill any RAID array.
If you're not going to use RAID you may as well go back into BIOS and turn the RAID function off (or switch it to AHCI only - whatever is available).
Plug your other drives back in and boot into Windows as normal.
You should be able to 'clean' the drive now.
